This quote from the 'Annals of Aman' might be worth bearing in mind at this point:
"Then the bliss of the Valar was increased, for the light of the Trees was holy and of great power, so that if aught was good or lovely or of worth, in that light its loveliness and worth were fully revealed, and all that walked in that light were glad at heart."
Telperion and Laurelin are more than just shiny plants! I couldn't find the quote but I even remember it being said somewhere that their light draws its source directly from the Secret Fire - the sacred source of Creation itself.
